Block inserter extraction

[immibis]

Could there be a way to prevent inserters taking items out of a particular entity? Ideally, it should be writable.

This is probably the simplest workaround to detect when an item is crafted, before an inserter can remove it. Otherwise, the inserter might remove the item before the Lua ontick event runs.
